description The aim of this study was to investigate how seasonal variations affect the quality of logging residues. The study was hosted by VIDA Energy. Logging residues can be processed and transported within different systems. Today the dominant systems are chipping at landing and bulk transportation of logging residues. In these systems the handling of the logging residues are carried out in the same manner up to the landings. Moisture content at the time of chipping is the primary quality parameter. Fine fractions of logging residues are strongly dependent on moisture content in storage. Another quality parameter is the natural ash content. What constitutes good fuel quality has no simple answers. Costumer’s requirements are often a determining factor. The heating stations have different prerequisites because the boilers and the systems of the heating stations are different. The quality of logging residues at the time for piling storage seems to determine the quality at chipping. Low moisture at the piling results in low moisture content at chipping. Seasonal impacts during forwarding has effects on moisture content, but heavy precipitation in connection with the forwarding appears to influence the moisture content negatively even when forwarding during the summer season. Long periods with heavy precipitations before chipping appears to affect the moisture content negatively as well.
